Problems solved by technology

However, it is time-consuming and labor-intensive to grind the paving materials by hand. At the same time, there are disadvantages such as insufficient grinding, uneven mixing, air bubbles in the material, and uncontrollable thickness of the paving materials each time.
Manual planking will cause the board surface to be uneven, inconvenient to take, variable and other shortcomings
The natural drying process takes a long time and many variables are uncontrollable, which has a great impact on the experiment
At present, the existing thin-layer chromatography planking machine does not have a complete set of equipment, and most of them separate the steps of grinding materials, cutting and laying, removing and drying, which is not intelligent, accurate and professional, and cannot save manpower and material resources to the greatest extent.

Embodiment 2

[0025] Example 2. One-time automatic preparation of 30 chromatography plates with a thickness of 2mm and a size of 10cm*20cm

[0026] When the program setting requires 30 chromatographic plates with a thickness of 2mm and a size of 10cm*20cm, 30 glass plates are placed in the storage tank 8, and the required materials are poured into the mixing tank 3. The program starts, the materials are uniformly mixed by ultrasonic and air bubbles are shaken. At the end of the set time, the spiral column 9 adjusts the glass sheet to a position 2mm from the horizontal plane of the fixing table 7. At this time, a No. Ⅱ 10cm blanking port 4 is used, and the four parts of the fixing table 7 are in accordance with the size of the glass sheet. Adjust to a suitable size, the mixing tank 3 and its connected discharging port 4, and the scraper plate 5 move from left to right until it touches the contact sensor 1 on the right, so that the screw column 9 is screwed up to the bottom of the glass sheet. ...

Abstract

The invention belongs to the technical field of thin layer chromatography preparation devices for chemical experiment and particularly relates to a fully-automatic thin-layer chromatography planking machine. The fully-automatic thin-layer chromatography planking machine is characterized in that a material mixing tank is positioned between two contact sensors and can move leftwards and rightwards on a supporting rod; the material mixing tank adopts a double-layer stainless steel plate, and an ultrasonic uniform mixing system is placed in an interlayer; materials are in full contact by using an ultrasonic vibration method; an automatic spiral column is adopted for regulating and controlling the planking thickness; a discharging port is used for smearing, a scraping plate is used for scraping and moving a thin layer chromatography plate, and a drying plate is used for drying. The fully-automatic thin-layer chromatography planking machine is small in size, high in efficiency and strong in practicability, homogenizes at a high speed, is free from dust and air bubbles and realizes planking integration and intellectualization.

Description

Technical field [0001] The invention belongs to the technical field of thin-layer chromatography preparation devices for chemical experiments, and specifically relates to a fully automatic thin-layer chromatography paving machine. Background technique [0002] The separation effect of TLC on the monomer components and the reproducibility of the results depend on the quality of the TLC. At present, the preparation of thin-layer chromatography mainly includes three steps: manual grinding of paving materials, manual paving, and natural drying. However, manual grinding of paving materials is time-consuming and laborious. At the same time, there are disadvantages of insufficient grinding, uneven mixing, air bubbles in the material, and uncontrollable thickness of the paving each time. Manual paving will also cause the board surface to be uneven, inconvenient to take, and easy to change. The natural drying process takes a long time and has many uncontrollable variables, which has a g...
